The nurse debriding a burn wound explains that the purpose of debridement is to:
increase the effectiveness of the skin graft.
promote movement in the affected area.
prevent infection and promote healing.
promote suppuration of the wound.
The Correct Answer is C
A. Increase the effectiveness of the skin graft:
Debridement can indeed increase the effectiveness of a skin graft by preparing a clean, viable wound bed for grafting. Removing dead tissue and debris helps the skin graft adhere to healthy tissue and promotes successful graft take. However, this is not the primary purpose of debridement.
B. Promote movement in the affected area:
While debridement can indirectly contribute to promoting movement by improving wound healing and reducing pain, the primary purpose of debridement is not to promote movement in the affected area.
C. Prevent infection and promote healing:
This statement accurately reflects the primary purpose of debridement. By removing nonviable tissue, debris, and foreign material from the wound, debridement helps prevent infection by reducing the bacterial load and creating an environment conducive to healing. It also promotes granulation tissue formation and wound contraction, which are essential for wound healing.
D. Promote suppuration of the wound:
Suppuration refers to the formation and discharge of pus from a wound, often indicating infection. Debridement aims to remove necrotic tissue and prevent infection, so promoting suppuration is not a desired outcome of debridement.

Correct Answer is C
Explanation
A. Superficial infections are caused by fungus.
While fungal infections can indeed cause superficial skin infections like tinea (ringworm) or candidiasis, they are not the common factor for the etiology and pathophysiology of folliculitis, furuncles, and carbuncles. These conditions primarily involve bacterial infections of the hair follicles, typically caused by Staphylococcus aureus bacteria.
B. Parasites get underneath the skin.
Parasitic infections can cause various skin conditions, but they are not the common factor for folliculitis, furuncles, and carbuncles. These conditions are specifically related to bacterial infections of the hair follicles rather than parasitic infestations.
C. Hair follicles are infected or inflamed.
This is the correct choice and the common factor for folliculitis, furuncles, and carbuncles. All three conditions involve the infection or inflammation of hair follicles, primarily due to Staphylococcus aureus bacteria. Folliculitis is the inflammation of one or more hair follicles, furuncles are deeper infections involving the hair follicle and surrounding tissue, and carbuncles are clusters of interconnected furuncles with deeper tissue involvement.
D. There is an allergic response to an allergen.
An allergic response to an allergen does not play a role in the etiology and pathophysiology of folliculitis, furuncles, and carbuncles. These conditions are primarily infectious in nature, involving bacterial colonization and subsequent inflammation of the hair follicles rather than an allergic response.
Correct Answer is D
Explanation
A. Cardiac arrest related to septic shock:
Septic shock can occur in burn patients due to the breakdown of the skin barrier, which allows pathogens to enter the bloodstream and cause systemic infection. However, while septic shock is a serious complication of burn injuries, it is not the primary cause of death in the emergent phase. Septic shock can lead to multiple organ failure and contribute to mortality, but it is often a later complication rather than an immediate cause in the emergent phase.
B. Infection:
Infections are a significant concern in burn patients, especially as the burn wound provides an ideal environment for bacterial growth. However, infections typically contribute more significantly to mortality in the later phases of burn care rather than in the emergent phase. In the emergent phase, hypovolemic shock and other immediate complications have a greater impact on mortality.
C. Adrenal failure:
Adrenal failure, specifically acute adrenal insufficiency or Addisonian crisis, can occur in burn patients due to the stress response and corticosteroid depletion. While adrenal insufficiency is a concern in severe burn cases, it is not the primary cause of death in the emergent phase requiring referral to a burn center.
D. Hypovolemic shock and renal failure:
Hypovolemic shock is a critical concern in the emergent phase of burn trauma because burns can lead to significant fluid loss and electrolyte imbalances. Hypovolemic shock results from insufficient circulating blood volume, leading to inadequate perfusion of organs and tissues, which can be life-threatening. Additionally, renal failure can develop due to hypovolemia, decreased cardiac output, and the release of inflammatory mediators, leading to acute kidney injury (AKI). Hypovolemic shock and subsequent renal failure are major contributors to mortality in the emergent phase of burn trauma, necessitating prompt referral to a burn center for specialized care.
